Your supply chain breaks down where humans are doing the work systems should handle
Most supply chain failures aren't caused by bad suppliers or unpredictable demand — they're caused by slow, manual processes that don't catch problems until they're expensive. Purchase orders go out late. Inventory reorder points are checked weekly instead of in real time. Supplier onboarding takes weeks because it requires chasing documents by email. We build supply chain automation that fixes these problems at the process level, not the headcount level.
Purchase orders generated and sent automatically when inventory hits reorder thresholds
Demand forecasting triggers that flag reorder decisions before stockouts occur
Supplier onboarding handled through a self-service portal, not email chains

Supply chains fail at the handoffs, not the hard parts
The complex parts of supply chain management — supplier negotiation, demand strategy, logistics network design — require human judgment. But most supply chain teams spend the majority of their time on work that doesn't: checking inventory, drafting purchase orders, chasing supplier documents, matching invoices, and generating compliance reports.
That's the automation opportunity. Not replacing the hard decisions — removing the manual overhead that delays them and makes them more expensive.
Capabilities
What we build
Purchase order automation
Purchase order automation triggers PO generation from inventory data without manual intervention. The automation monitors your stock levels via direct ERP integration (SAP OData/RFC, Oracle ERP Cloud REST API, NetSuite SuiteTalk/SuiteQL, Microsoft Dynamics 365 Business Central REST API, Odoo XML-RPC) or WMS data feed and compares current on-hand quantity against each SKU's reorder point. When stock crosses the threshold, a draft PO is generated pre-populated with the configured supplier, ordered SKU, quantity calculated from the economic order quantity formula or fixed MOQ rule, agreed unit price from the approved vendor price list, and delivery address. The draft routes through an approval workflow: value-based tiered approval (orders below £5,000 require single-approver sign-off; orders above £25,000 route to the procurement director and CFO); category-based approval for strategic or single-source categories requiring additional review; or straight-through processing for pre-approved routine replenishment orders below a configurable value threshold. On approval, the PO is transmitted via EDI X12 850 or EDIFACT ORDERS for suppliers with EDI capability, via email with a structured PDF template for email-based suppliers, or via supplier portal API for digital-native suppliers. Supplier acknowledgement is tracked: if a PO is transmitted but not acknowledged within the configured window, an automatic chase notification fires and the procurement team is alerted. Routine replenishment orders that run on identical terms every 30 days are the first target -- those POs should not require a human to generate them.
Demand forecasting and reorder triggers
Demand forecasting automation calculates forward-looking stock requirements per SKU using historical sales data and applies statistical adjustment for seasonality, promotional uplift, and lead time variability -- generating reorder recommendations before safety stock is breached rather than after. Forecasting methodology: simple moving average (7-day, 14-day, 28-day trailing) for stable-velocity SKUs; exponential smoothing (Holt-Winters triple exponential smoothing) for SKUs with trend and seasonal patterns; manual demand plan override for SKUs with upcoming promotions or product launches where historical data is not a reliable predictor. Reorder point calculation per SKU: average daily demand multiplied by supplier lead time plus safety stock (calculated as Z-score for the desired service level, typically 95% for A-category items and 90% for B-category, multiplied by the standard deviation of demand during lead time). When projected stock falls below the reorder point, the system generates a reorder recommendation with the suggested quantity, projected stock-out date under current velocity, and the supplier lead time -- your planning team reviews the recommendation in a queue rather than calculating it themselves. Reorder trigger rules are configurable per SKU, per category, and per supplier: an item with a 45-day supplier lead time has a different trigger threshold than one with a 7-day lead time. Seasonal profile calibration: the system allows you to define demand multipliers by week of year for each product category so the forecast model accounts for Christmas demand peaks, summer slowdowns, and other predictable patterns that a trailing average would underpredict or overpredict.
Supplier onboarding portal
Self-service supplier onboarding portal that replaces the email-and-attachment workflow with a structured, trackable process. The portal is accessed via a unique onboarding link sent to the new supplier; no login to your internal systems is required. Supplier self-service steps: company registration details (name, registration number, VAT/GST number, registered address), bank account details (IBAN/SWIFT for international, sort code/account number for domestic, validated against your bank's account verification API via TrueLayer or Modulr), primary contacts, and document uploads. Required document types are configured per supplier category: ISO certifications, public liability insurance certificates, conflict minerals declarations, modern slavery policy, data processing agreements, and product compliance certificates (CE marking, FDA approval). Document completeness check runs automatically on each upload: required documents are listed with a status indicator (uploaded/pending/expired), expiry dates extracted from certificates using OCR (Azure Document Intelligence or Google Document AI), and an automatic reminder sent to the supplier if required documents are missing 48 hours after the onboarding link was opened. Complete submissions route to your procurement team's review queue as a structured summary -- supplier information, document thumbnails with expiry dates, and company registration verification -- rather than an inbox full of attachments. Approval triggers automatic ERP record creation (supplier master data entry in SAP, Oracle, NetSuite, or Dynamics via API) so the new supplier can receive POs immediately after approval without manual data entry. Re-onboarding automation: expiring certifications trigger advance renewal requests to the supplier 90, 60, and 30 days before expiry so compliance documentation stays current.
Inventory monitoring and alerts
Real-time inventory monitoring watches every SKU continuously against configurable thresholds and fires targeted alerts with enough context to act -- not a raw data export requiring a planner to identify the exceptions themselves. Monitoring dimensions per SKU: on-hand quantity vs reorder point (alert when below reorder point, with days-of-cover calculation at current velocity); days-of-cover at current velocity (alert when below configurable threshold -- e.g., less than 14 days cover on an A-category item); overstock alert when on-hand quantity exceeds maximum stock level (calculated as reorder point plus order quantity); expiry monitoring for perishable goods and dated products (alert 30, 14, and 7 days before expiry date, with quantity and storage location included); and slow-mover detection (SKUs with zero or near-zero sales velocity for 30+ days flagged for review to identify dead stock before it becomes a write-off). Alert routing: critical stockout risk (less than 7 days cover on an A-category SKU) alerts the supply chain manager and procurement lead immediately via Slack and email with a pre-populated reorder recommendation. Non-critical alerts (standard reorder point breaches) go to the daily exception report delivered each morning with all action-required items ranked by urgency. Location-level monitoring for multi-warehouse operations: alerts include which warehouse is low while other warehouses may have surplus, enabling inter-warehouse transfer as an alternative to a supplier reorder. WMS integration for live data: SAP Extended Warehouse Management, Oracle Warehouse Management, Manhattan Associates WMS, Fishbowl, or direct database connection for smaller operations.
Goods receipt and three-way matching
Three-way matching automation compares purchase orders, goods receipt notes, and supplier invoices in real time -- clearing matched invoices for payment automatically and flagging discrepancies with the variance pre-calculated and source documents attached. Invoice ingestion: invoices received by email are extracted using AI-based OCR (Azure Document Intelligence or AWS Textract) that identifies PO number, supplier, line items, quantities, unit prices, and total; invoices received via EDI X12 810 or EDIFACT INVOIC are parsed directly. The extracted invoice data is matched against the corresponding PO retrieved from the ERP and the GRN logged by the warehouse receiving team. Match criteria: PO number match (extracted from invoice vs ERP PO record); line item quantity match within configurable tolerance (typically ±1% for weight-based goods, exact match for discrete unit goods); unit price match against the agreed price on the PO (flagged if supplier has invoiced at a different price than the approved rate); and total invoice amount reconciliation. Matching outcomes: full match within tolerance -- invoice cleared and approved for payment, forwarded to accounts payable with matched reference; quantity variance -- discrepancy pre-calculated per line item, routed to the warehouse or procurement team to verify whether additional goods were received or are in transit; price variance -- invoiced price vs PO price shown side by side, routed to procurement for supplier query or price update; missing GRN -- invoice received for goods not yet receipted, held in a pending queue with an alert to the warehouse. Audit trail per invoice: every matching decision, tolerance applied, and approver action is recorded for accounts payable audit purposes and supplier dispute resolution.
Supplier performance tracking
Supplier performance scorecards built on data that already exists in your ERP, WMS, and quality systems -- consolidated automatically at period close rather than requiring a procurement analyst to pull data from four systems and assemble a spreadsheet. Metrics calculated per supplier per period: on-time delivery rate (PO line items delivered by promised date / total line items, with a configurable grace window of 1--3 days); on-time in-full (OTIF) rate (line items delivered on time and at the correct quantity); quality rejection rate (units rejected at goods receipt inspection / total units received, sourced from QC system); invoice accuracy rate (invoices matched first-pass vs total invoices, from three-way matching data); lead time accuracy (actual lead time vs stated lead time on PO acknowledgement); and price compliance rate (invoiced price vs contracted price, from three-way matching variance data). Scorecard calculation runs automatically at month end or can be triggered on demand. Scorecard delivery: each supplier's procurement contact receives their performance summary via email; the procurement team receives a ranked scorecard across all suppliers with performance trend arrows (improving/declining/stable) and an exception flag for suppliers below configurable thresholds on any metric. Performance data is used to populate supplier review meeting agendas automatically -- the system generates a meeting pack with the supplier's scorecard, trend analysis, open claims or disputes, and outstanding POs for the procurement team's quarterly review. Sourcing decision support: when evaluating alternative suppliers for a category, the scorecard history for all suppliers in that category is presented side by side as part of the sourcing analysis.

Frequently asked questions
Purchase order automation consistently delivers fast, measurable returns because the volume is high and the manual cost is visible. Every PO that requires a human to check inventory levels, draft the order, get approval, and send it to the supplier carries a cost in time and delay. Automating the trigger, draft, approval routing, and transmission cuts that cycle from days to minutes for routine orders. Three-way matching is another high-return target — manually matching purchase orders, goods receipts, and supplier invoices to catch discrepancies is time-consuming work that automation handles in real time, flagging only the exceptions. Inventory monitoring and reorder alerts prevent the most expensive supply chain failure: stockouts on high-velocity items that should never run dry but do because nobody checked in time. These three, combined, typically justify the automation investment within the first two to three months of operation.
The automation monitors your inventory data — either directly from your ERP or WMS, or from a data feed — and compares current stock levels against your defined reorder points and lead times. When a threshold is crossed, the automation generates a draft purchase order using your standard template, pre-populated with the correct supplier, SKU, quantity based on your reorder rules, and delivery address. It routes the draft through your approval workflow (single approver, tiered approval by value, or straight-through for low-value repeat orders), and on approval sends the PO to the supplier via email or EDI. The supplier confirmation comes back and updates the expected delivery record. Your procurement team reviews exceptions — urgent orders, supplier substitutions, pricing anomalies — rather than processing every PO manually. The trigger logic, approval rules, and supplier routing are all configurable and defined during the scoping phase.
Manual supplier onboarding typically looks like this: someone sends an email asking for documents, the supplier replies with some but not all of them, someone chases the rest, someone validates the documents, someone enters the data into the ERP, and two weeks later the supplier is approved. Automation replaces that with a self-service supplier portal where the supplier enters their own data, uploads the required documents (certificates, bank details, insurance, compliance declarations), and the system validates what it can automatically — company registration checks, bank account format validation, document completeness. Incomplete submissions trigger automatic reminders. Complete submissions are routed to your procurement team for a final review with a structured summary rather than a pile of attachments. ERP data entry is handled automatically on approval. Onboarding time typically drops from two to three weeks to three to five days.
Yes, that's the standard integration model. We don't replace your ERP. We connect to it. Most supply chain automation projects involve reading data from the ERP (inventory levels, open POs, goods receipts), applying business logic outside it, and writing results back in (new POs, matched invoices, supplier records). We've integrated with SAP, Oracle, NetSuite, Microsoft Dynamics, Odoo, and several industry-specific ERP platforms. If your ERP has an API, we use it. If it uses EDI for supplier communication, we work within that standard. If your current integration is primarily CSV exports, we build around that. The integration approach is scoped in the first two weeks of the project and agreed before development starts. We flag integration risks early — there are no mid-project surprises about what your system can or can't expose.
